I should mention that the other approach to the same end is to start a 
new 'experiment' file that starts with what might be the minimum and 
adds more only if the error is not reproduced.  I sometimes do this with 
posted SO code.  With tkinter questions, 10 lines (versus an original 
and incomplete code of, say, 50 lines) is typically enough.  Answering 
with such an MCVE, along with the usually simple fix, focuses attention 
on the particular issue
